Transfer of large amount of data from one computer to another has always created problems, one of main reason being non-availability of suitable data storage device. To be precise, Storage mediums like floppy, CD and even Email have always failed during urgency due to their problem causing ability like small storage space or time-consuming ability for data transfer.
A possible solution to end this problem is use of zip drive. With up to 250MB capacity we can store everything we want and more on it. But in order for a proper transfer process to take place, both the computer systems must have zip drives. In addition, it more expensive compared to old floppy disk system. So what is the remedy to all these problems?
Pen Drive is the solution to the problem. Pen Drive can hold more data compared to floppy disk and Email space. Basically, Pen drive is a small key-ring-size device that can be used to easily transfer files between USB-compatible systems. It is accessed through the USB port on the computer. It has a capacity to hold data ranging from 11 to 350 floppy disks depending on the memory stick you choose. You can transfer data faster and easier than ever before. Pen drives are faster than downloading data via e-mail and much easier than using boxes of floppies. They are no bigger than the length of your finger, but hold data from 16 MB to I GB.
USB pen drives provide data, music and video transfers and storage with plug-and-play ease. The best feature of Pen Drive is that it doesn`t require any software to work, enabling the process of reading, writing and copying to or from a disk drive simple. Furthermore, it also doesn`t require any battery to operate. Hence, a pen drive is totally portable. Attach it to your key chain, belt, or wear it around your neck.
Basics about universal serial bus (USB) required for Pen drive.
USB is an external peripheral interface standard developed by the computer industry to allow communication between a computer and external peripherals (digital device) over a cable using bi-serial transmission. Usually, digital cameras and memory card readers connect to the USB port on a computer. USB card readers are typically faster compared to cameras or readers that connect to the serial port, but slower than those that connect via FireWire.
The USB port is usually found at the back of the PC. It is a narrow socket around 1cm wide and 0.5cm high. You can plug a USB pen drive only into USB port. In some PCs, the USB port is located on the front below the CD-ROM drive.
For Windows 2000, XP, or ME USB driver need not be installed manually as the operating system will do it automatically. But, in case of Windows 95/98/98SE, drivers need to be installed manually (the driver is supplied along with the drive).
How to use it?
To transfer required Data of a P.C into Pen drive or vice-versa, simply plug the Pen drive into the USB port of your PC. The operating system will automatically detect installation of a new device and a new drive will be created. The operating system can access your pen drive just like any ordinary hard disk drive.
Now, Copy all the required files you want into the `new` drive and wait for the response by the Pen drive--indicated by read/write LED on the pen drive, to stop flashing and then disconnect it. Your files are now safely stored on your pen drive. If you want to copy these files to another PC/ Mac, just plug the drive in the new machine, wait for it to be detected and copy the files.
Working and cost
The working of Pen drive is based on flash memory. The flash memory-a type of EEPROM (Electrically Erasable Programmable Read Only Memory) chip.
Basically, EEPROM is a type of ROM that can be erased electronically and reprogrammed in-circuit (or with a device programmer) consisting of a complex grid of columns and rows. Hence, bytes (words) of an EEPROM can be erased individually.
The main reason why flash memory is quicker than older EEPROM is that entire banks can be erased at a time and subsequently rewritten.
The 32MB pen drive costs around $15, while the 1GB pen drive costs as high as $100; however, the purchase is worth the money.
Transparent pen drive
Flash Dio is a transparent pen drive. Frankly speaking, there is hardly any difference between the two except for few new features such as extra protection for write/delete switch from accidental erases.
